The Rinnai E boiler is a room sealed, condensing

and modulating central heating boiler with an

integrated hot water facility.

The boiler is provided with a integrated control

system. Because an outdoor sensor is connected

to the boiler, the boiler works weather dependantly.

This means that the boiler control measures the

outside temperature and ﬂ ow temperature. With

this data the boiler calculates the optimal ﬂ ow

temperature for the installation.

When the boiler is connected to an RS100 room

thermostat information can be retrieved from the

boiler. For more information about the Rinnai

thermostats. Please refer to the user manuals.

On the bottom left side of the front panel there is a

small door. Through the transparent panel you can

see the boiler status on the display. After opening

this door you will ﬁ nd the function buttons.

On the following pages you will ﬁ nd the explanation

of the function buttons and display messages.

Explanation of the function buttons

Only licensed professionals who are trained for

these boilers are permitted to make alterations

in the controller to program the boiler to the

installation.

1. Display.

See following pages for further information.

2. ON-OFF Switch (Placed separately next to

the boiler). This switch turns the power supply

to the boiler on or off.

3. Central Heating program button.

Switching the Central Heating on or off (Led

on/off);

4. Hot Water program button.

Switching the Domestic Hot Water (DHW)

facility on or off (Led on/off);

5. Pump program button.

When the pump program LED is ON, the pump

is switched into a continuous circulation mode.

When the pump mode is switched OFF, LED is

off the pump is control by the boiler processor.

Do not activate the pump program button. Call

your licensed professional before if alterations

to the boiler are required.

During freezing temperatures it is possible (when

there is no outside sensor connected), to manually

place the circulation pump in constant circulation

mode, thus reducing the chance of freezing pipes

(garage, attic or other cold spaces / rooms) which

are sensitive to frost.

When the pump is switched

on continuously it can lead to

undesired heating up of the

central heating system during

the summer and adversely

effect the boilers operation.

The boiler display

Two boiler displays, “Good or Technical” see below.

Good

or standard read out.

During this reading the display will only show what

is necessary. Under normal circumstances the

display will give a Good reading. In case of a

fault this will be shown with, alternate display of

Good, with an E or BL code. See further "Errors,

maintenance and warranty" .

Technical

The second way is a technical read out. In normal

situations the following will be shown:

• on the left the status in which the boiler is active

(see bottom of this page);

• on the right the supply temperature in °F;

• the water pressure in the installation in PSI.

When a message (E or BL code) is necessary this

will be shown instead of the technical read out.

To switch over from the Good-state to the

Technical read out (and vice versa):

- Press 5 sec. on the STEP-button.

Water pressure in the central heating system

The installation will function optimally with a water

pressure of between 16 and 18 PSI.

If the water pressure drops below 16 PSI, the

display will show FILL. During this message the

boiler will remain functioning at a reduced level.

After replenishing the system (see following

chapter) just above 22 PSI the message FILL

will disappear and the boiler will function normally

again.

When the water pressure drops below 10 PSI, the

display will show a ﬂ ashing FILL text.

The boiler will shut down and will function normally

again after replenishing the system to just above

22 PSI.

To retreive the water pressure on the display from

the Good reading:

- Press the Step key once brieﬂ y.

The water pressure will be shown.

Press the Step key brieﬂ y to return to the Good

reading.

Water pressure is too high (>42 PSI), if HIGH

indication remains continuously visible, the boiler

is taken out of operation. The installation pressure

needs to be decreased by draining water until the

pressure is between 16 and 18 PSI.

Message ' Water pressure

too low' on your RS100

thermostat.

On the display of the RS100

a low water pressure can

be indicated. For further

information see the relevant

user manual.

Operating instructions Rinnai E-Series

Replenishing the central heating system

The central heating installation needs to be ﬁ lled with potable (drinking)

water. For topping up the installation you use the ﬁ lling loop according to the

following procedure:

Contact your licensed professional installer if

your installation is not provided with a ﬁ lling

loop.

1 Switch all functions off (heating, DHW and pump);

2 Brieﬂ y push the 'STEP'-button: P x.x = water pressure in PSI;

3 Slowly open the ﬁ lling loop (Indication on display increases);

4 Fill up slowly to between 16 and 18 PSI;

5 STOP appears on the display;

6 Close the ﬁ lling loop;

7 De-aerate the complete installation , start at the lowest point;

8 Check the water pressure and if necessary top it up;

9 Close the ﬁ lling loop;

10 Activate functions required (heating

, DHW and/or pump );

11 If A xx appears on the display, wait for 17 minutes;

12 Check the waterpressure and if necessary top it up to 16 to 18 PSI

13 Close the ﬁ lling loop;

14 Press the ‘STEP’-button;

15 Be sure that the ﬁ lling loop is closed.

After the automatic de-aeration programm (A xx) is ﬁ nished the boiler will

return to the Good reading or Technical reading.

Holiday period:

Adjust the thermostat* to the holiday period. See

the user thermostat manual. The hot water facility

can be switched off by means of the program

button on the control panel.

Re-setting the central heating system:

Switch off the three program buttons , ,

when these are activated. Switch off the power

supply. When the boiler is being drained one

should take into account that a part of the heating

water will remain in the boiler. When risk of freezing

arises one should take care that the remaining

central heating water in the boiler does not freeze.

Holiday

* If you have a RS100

thermostat it is provided

with a holiday program.

The holiday period can be

adjusted on the thermostat

itself. The central heating

and DHW supply are

switched off during that

period. There is also the

option that only the central

heating is switched off. With

all of these possibilities the

freeze protection system

is active.

The boiler will not function directly. The automatic de-aeration program of about

17 minutes will start after one of the three program buttons is pressed. The display

will show where A stands for Automatic de-aeration program Active and

the number on the right indicates the actual water temperature of the boiler.

Check the water pressure regularly and top up the installation when

necessary.

The working pressure of the installation should be between 16 and 18 PSI

It can take a while before all air has disappeared from a ﬁ lled installation.

Especially in the ﬁ rst week noises can be heard which indicate the presence of

air. The automatic air vent in the boiler will remove the air, which means the water

pressure will reduce during this period and therefore topping up with water will

be necessary to adjust the ﬂ ow water temperature
